AWS Route 53 Email DNS: MX, SPF, DKIM for OquMail
Publish mail authentication records in Route 53 hosted zones — TTL tips, TXT record splitting, and verification workflow.
Startups on AWS often register domains in Route 53. Email DNS is standard — MX plus TXT — but long DKIM keys sometimes need careful quoting in the console.
Route 53 specifics
- Create MX records (the settings that tell the internet where to deliver email for your domain) set with priority 10
- TXT for SPF — one string, 255 char limit per line if splitting
- TXT for DKIM at selector subdomain
- Lower TTL to 300 during migration, raise after stable
- Use OquMail verify to confirm public DNS matches
